I do not understand the whole concept of molar conductivity, including the behavior of strong and weak electrolytes in a conducting solution. Why does the molar conductivity of strong electrolytes increase slowly and weak electrolytes increase steeply. Please help.

for strong electrolyte the disscociation is constant for a wide range hence you get a straight line b/w conductivity and concentration
but for a weak electrolyte the disscociation constant is low for normal concentrations
but due to dilution this constant increases non-linearly hence molar limiting conductivity cannot be just obtained by extrapolating the graph, the number or ions per volume increases tremendously...

hope you got it
